Implement numpy-compatible array joining routines in numojo/routines/manipulation.mojo: - concatenate(): Join arrays along an existing axis - column_stack(): Stack 1-D arrays as columns into 2-D, or hstack 2-D+ arrays - row_stack(): Stack arrays vertically (1-D reshaped to (1, N)) - hstack(): Horizontal stacking (axis=0 for 1-D, axis=1 for 2-D+) - vstack(): Vertical stacking (alias for row_stack) All functions are exported via numojo.routines and numojo top-level. Tests validate against numpy equivalents for 1-D, 2-D, 3-D, and mixed-dimension inputs.
